We have been studying aircraft propulsion systems in my thermodynamics class the past two weeks, and i just had a quick question about what my professor said about turboprops.
In a turbofan engine the turbine is designed to provide just enough power to run the compressor, the fan, and any auxillary equipment. The rest of the combusted gases exit out the nozzle as thrust. I understand that no problem. Then my professor says that a turbo prop is designed the same way, only there is no cowling over the fan. Meaning that it is still powered by thurst and the prop on the front just gives it a very high bypass ratio. I had always thought that in a turboprop, the turbine was designed to convert all of the energy from the combusted gases to turn the prop through a gear reduction and the thurst is negligeble.
any turboprop pilots care to help? thanks
